Other Accessories

Various motion control accessories can be obtained or manufactured for specific requirements in visual effects, special effects and camera control.

MRMC make their own zoom, focus and iris motors. The current design is compact, robust and powerful, and unlike Preston and other types of motor, can be moved by hand for quick setting, and recording of live moves. An interface also allows the familiar Preston or Arri control units to be used as input devices for live operation.

A trigger unit is available that sends and receives GPI signals to synchronize to external events. It can also trigger relays to switch devices powered by AC or DC voltage.

In addition this unit has a camera stop/start function, a shutter pulse input for jamming to camera exposure timing, and a bloop light output for visually marking any part of a recorded sequence.
